A friend of mine suggested that I look into a roller cam for my 350 SBC build. My block is a 1977 and I have Edelbrock RPM heads and manifold for it, Scat crank, TRW 10:1 pistons. I have been searching all over for some info on just what would need to be modified to use a roller with no luck. Thanks to anyone that can point me in the right direction. Just curious.... have any of you ever converted to a roller? Did you gain much compared to the trouble? Is it a worth while move? Thanks
